Conversational turn-taking feels effortless, but it's a complex dance. We find social context—who you're talking to and what you're talking about—fundamentally changes conversational dynamics in both autistic & TD children. 1/

Social Context Matters for Turn‐Taking Dynamics: A Comparative Study of Autistic and Typically Developing Children

Engaging in fluent conversation is a surprisingly complex task that requires interlocutors to promptly respond to each other in a way that is appropriate to the social context. In this study, we dise...

📢Our peer-reviewed article about the AffectTracker is finally out! 😲🕹️📈
Traditional methods for rating emotion often miss the dynamic, moment-to-moment nature of feelings. We designed a tool to capture this continuous affective experience in real-time during dynamic emotional stimulation.

Frontiers | AffectTracker: real-time continuous rating of affective experience in immersive virtual reality

Subjective experience is key to understanding affective states, characterized by valence and arousal. Traditional experiments using post-stimulus summary rat...

Besides replicating our previous study doi.org/10.1016/j.bi...
, we also made an interesting observation:

When sending an emoji per button press we found an increase in EMG activity in the corresponding facial muscle

This work originated in a undergrad course on experimental psychology. I'm super proud of my students (and now co-authors) who continued to work on this with me - even when the course was long over

I've said it before, and I will say it again:

It's astonishing how emotionally aversive revisions are, even in the best possible case (reviewers are positive and have very actionable remarks).

Or at least that's how I work; if anybody has some good recommendations for coping, do let me know 😂

But the personas also influenced participants' behavior Participants also talked more when conversing with teh extraverted vs. introverted agents

Leon Kroczek @leonkroczek.bsky.social · Aug 4

Interestingly, the two personas changed how participants evaluated the virtual agent: The extraverted model was rated as more pleasant.

Leon Kroczek @leonkroczek.bsky.social · Aug 4

The LLM was prompted to be either extraverted and talkative or introverted and less talkative.

Using the NEO-FFI as a manipulation check confirmed these differences. The extraverted model also produced more words

By combining speech2text, speech-synthesis, and lip-synced animations for #Metahumans our participants engaged in real-time conversations with a virtual human

I might be biased, but what an inspiring #VR symposium at #PuG25 🤩
This field still develops so fast 🚀as showcased by the integration of neurophysiology, multi-user settings and clinical application.

New preprint!

Here we investigate sustained threat responses elicited by social contexts in #VirtualReality looking at:

🧠🌊 Neural Oscillations
🔊Fear potentiated startle
💦 SCL
🗓️Self-report

All measures show successful fear learning by social contexts ✅
